</span> All normal eggs from the mother have an X chromosome while usually half the sperm cells from the father have a Y (male) chromosome and the other half have an X (female) chromosome and it is therefore the father's sperm that dictates which gender the embryo will take.
If the egg is fertilized by a sperm with a Y chromosome then the embryo will be a genetic male due to XY chromosome combination.
<span>If the egg is fertilized by a sperm with an X chromosome then of course the embryo will be a genetic female due to XX chromosome combination.</span>
DNA is nothing more than a sequence of bases (nucleotides) and since DNA is normally double stranded, they can be referred to as base pairs. One could best visualise it like a zipper: two connected strands (that can also be separated). DNA is made up of only four different bases, abbreviated as A, C, G and T. These always form the same pairs: A on one side of the zipper, T on the other side and the same goes for C and G. So, when unzipped, you always know the sequence of the opposite strand.
The sequence of base pairs that make up our DNA should be viewed like a bar code. Every set of three bases code for one building block of a protein. That's all that DNA is for: code for building proteins. A set of three bases is called a codon and tells machinery in the cell (ribosome) to add one specific building block to a forming protein. It's like Lego and DNA is the instructions that tell you which block to add next.
These different blocks give shape and function to the proteins it helps to build.
Answer: a.
Explanation:
The proficiency to be more professional and confident using one hand instead of the other for activities such as writing and throwing a pitch is called handedness.
Handedness begins to develop before birth. Handedness is inheritable and evident from early childhood. handedness is related to variations between the brain's right and left halves (hemispheres). The<em> the left hemisphere regulates the action of right side of the body while right hemisphere controls movement on the left side of the body</em>.
So in handedness, one half of the brain regulates more skilled motor action.
Hence, teh correct option is a.
Explanation:
no, we can not see radio waves. radio waves have the longest wavelength out of all the waves on the electromagnetic spectrum. we can only see visible light, which is towards the middle of the spectrum. the waves below or above visible light on the spectrum have wavelengths that are too long or short for the human eye to detect.
